A hand tool comprising a longitudinal alignment edge which facilitates alignment of the hand tool with an edge of sheathing. A measurement plate extends normal to the alignment edge. At least one of the alignment edge and the measurement plate contain indicia indicating a centerline of the hand tool. The measurement plate has at least a first pair of parallel marking edges, that are equally spaced from the centerline, to facilitate marking of a pair of alignment lines for use in aligning a framing member between the alignment lines during installation of the sheathing.
